[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] See also Figure 1-4 As shown, a multi-purpose quick-dismantle grounding device is provided, wherein a jack 2 is fixed to the top side of the base plate 1, a top plate 3 is fixed to the top of the jack 2, a connecting plate 4 is fixed to the side of the top plate 3, a supporting claw 6 is fixed to the bottom of the connecting plate 4, and a clamping structure 7 is symmetrically provided on the side of the supporting claw 6.

[0025] The clamping structure 7 comprises a rotating plate 71 in which a threaded rod 72 is rotatably mounted through threaded engagement.

[0026] A nut 76 is fixed to one end of the threaded rod 72, and a push plate 74 is rotatably connected to the other end of the threaded rod 72. When the grounding rod is disassembled, the bottom plate 1 is placed close to the ground, and the top plate 3 is lowered under the action of the jack 2. With the cooperation of the connecting plate 4, the claw 6 is placed close to the ground. After the bottom plate 1 and the claw 6 are placed close to the ground at the same time, the bottom plate 1 is pushed, thereby pushing the claw 6, which is convenient for the subsequent removal of the grounding rod.

[0027] A notch is provided on one side of the bottom plate 1 , the width of which is greater than the width of the claw 6 , so as to ensure that the claw 6 and the bottom plate 1 are simultaneously placed on the ground before use, so as to better clamp the grounding rod.

[0028] The open end of the claw 6 is in the shape of a vice, and the claw 6 and the connecting plate 4 are welded and fixed. After the claw 6 is pushed in, the end of the grounding rod will be stuck in the open position of the claw 6. By rotating the threaded rod 72 with the cooperation of the nut 76, the distance between the push plate 74 and the grounding rod is adjusted, and the push plate 74 is rotated until the grounding rod is clamped by the push plate 74. The lifting of the claw 6 can be driven by the operation of the jack 2 to lift the top plate 3, and the grounding rod can be pulled out with the cooperation of the clamping structure 7. The jack 2 can provide a stable lifting force. At the same time, the grounding rod has a stable movement process when it is pulled out and will not fly under the action of inertia. The operation is safe, the overall structure is compact, and it is easy to operate. It can also realize the removal of other rivets and has a wide range of uses.

[0029] The rib plate 5 is used for connecting and fixing the connecting plate 4 and the supporting claw 6. The two direct edges of the rib plate 5 are respectively used for connecting the connecting plate 4 and the supporting claw 6, which can ensure the stable rise of the supporting claw 6 when the jack 2 acts.

[0030] The clamping structure 7 also includes a tooth plate 73, which is fixed to the side of the push plate 74. The contact area between the tooth plate 73 and the grounding rod is small, and the pressure generated is large, which can clamp better. At the same time, the push plate 74 can rotate, and the shape of the tooth plate 73 can be adjusted to facilitate horizontal or vertical clamping. The bottom side of the rotating plate 71 is connected to a rotating column 75, and the bottom end of the rotating column 75 is rotatably mounted on the top side of the open end of the supporting claw 6. After the supporting claw 6 clamps the grounding rod, with the cooperation of the rotating column 75, it can ensure that the push plate 74 moves better in the direction of the center of the grounding rod during extrusion, thereby ensuring the clamping effect of the push plate 74 on the grounding rod, reducing slippage, and achieving better clamping.

[0031] The clamping structure 7 is located at the four corners of the opening of the claw 6, and a socket 77 is provided in the nut 76. The hexagonal nut 76 is prone to thread slippage during rotation, and the socket 77 can better ensure the rotation state of the threaded rod 72, and can also be tightened by other workpieces to improve operability.
